Question

Match the items in Column A with the items in Column B

Column A	Column B
1. Good conductor	a. Heat convector
2. Convection	b. Aluminium
3. Radiation	c. Ebonite
4. Insulator	d. Thermometer
5. Alcohol	e. Room heater

Accepted Answer

01. Good conductor - b. Aluminium
Aluminium is a metal and metals are good conductors of heat. They allow the flow of heat through them easily. The heat flow in conductors takes place without the actual movement of particles.

2. Convection - a. Heat convector
Heat transfer in a heat convector takes place through convection. The heat convector heats the air near it. The warm air has a density less than colder air and hence rises up. As the heated air rises up, the colder air moves towards the heater. The cold air is then heated, causing it to rise, and the cycle continues.

3. Radiation - e. Room heater
Heat transfer in a room heater takes place through radiation. The heating element in a radiator radiates heat into the room. The heat radiations fall on the objects in the room, which absorb some of these heat radiations and become warm. A heat radiator directly warms the objects and people in the room without heating the air in between.

4. Insulator - c. Ebonite
Ebonite is an insulator. Insulators do not allow the flow of heat through them.

5. Alcohol - d. Thermometer
Alcohol is used as a thermometric liquid in thermometers. It has a low freezing point ( $- 117 ° C$ ) and is generally used when low temperatures need to be measured.
